Tobacco pipe



H. TAYLOR TOBACQO PIPE Filed Sept. 13'. 1938 INVENTOR ATTORNEY PatentedOct. 1, 1940 UNITED-STATES PATENT I OFFICE.

My invention relates to improvements in tobacco pipes comprising amethod of and construction of elements for controlling the quantitles ofnicotine and moisture content in the products of combustion by means ofa temperature reducing condenser positioned in the stem of said pipesbetween thetobacco bowl and the mouth piece.

My invention relates to a condenser positioned in the stem of a tobaccopipe comprising a chamber communicating with the fine to. the tobaccobowl on one side and with the flue toj the mouth piece on the other sidethereof, a baflie, preferably of tubular construction and of selectedthermal conductivity, positioned transverse to and across the path ofthedraft from one portion of the flue to the other, with means toradiate and conduct the heat from said baffle tothe outside atmosphere,and means to trap condensed moisture and nicotine in a removablereceptacle at the base of said chamber.

My invention relates also to a tobacco pipe assembly comprising atobacco bowl with a short shank to which an elongated stem of plastic orrubber material is engaged and a condenser located in said plastic stemnear the bowl end thereof.

I attain these objects by the mechanism illustrated in the accompanyingdrawing, in which Figure l is a side elevation of a tobacco pipe showinga knurled cup of a condenser in the base of the stem.

Fig. 2 is a sectional elevation of a tobacco pipe showing theconstruction of a condenser in the stem thereof.

Fig. 3 is an enlarged sectional elevation of condenser having a tubularbaflle installed in fragmental pipe stem.

Fig. 4 is an enlarged sectional elevation of condenser having a solidbaffle installed in fragmental pipe stem.

Fig. 5 is an enlarged sectional elevation of a condenser chamber,without a baffle, but with a removable cup at the base of said chamber,in a fragmental portion of a pipe stem.

Fig. 6 is a side elevation of a removable tubular baffle with areservoir cup surrounding the base thereof.

Fig. 7 is a side outline elevation of a pipe with a condenser cupinstalled in the shank of a tobacco bowl.

Similar numerals refer to similar parts throughoutthe several views...

In order to increase the condensation of mois-' ture and theprecipitation of nicotine, tobacco tar, and other harsh elements fromthe products 5' of combustionlin a tobacco. pipe a condenser is providedinstem I adjacentto shank I of bowl 2, and comprises bafile3 preferablyof tubular construction, extending vertically through. coilof the draft,which is drawn from bowl ,2, impinging on baffle 3, traveling around it,and exhausts through flue, section" 5' and mouth piece B Bafile 3extendsvertically from the base of a cup shaped reservoir 8 and isintegral there-- 15 with and is," held A in place byfmanually turnin theknurled suriaceot cup 8;;thus screwing thef upperthreaded' end of'b'affl3 into a threaded aperture at 9 in the upper end of chamber 4, engagingthe rim ID of cup 8 against annular 20 seat H surrounding the lower endof chamber 4. The moisture content of the hot products of combustiondrawn from the base of bowl 2 through flue 5 partly condenses into aliquid when said products impinge on baflle tube, because the 25 heatthereof is absorbed by, conducted through and radiated from said tube 3to the outside atmosphere both by the circulation of air through saidtube and the exposure'of the outside of cup 8 to the outside air. Thislowering of the tem- 30 perature of the products of combustion causesthe precipitation of the nicotine laden moisture therefrom. Not all ofthe moisture is precipitated while the products are passing throughchamber 4 but continues to precipitate for a short distance in flue 5'and drains backinto reservoir cup 8 which forms atrap for retaining theliquid condensation against flowing into the base of the tobacco bowl 2or into mouth piece 6; thus insuring a dry bowl and a mouth piece freefrom 40 liquid. Wall l6 of chamber 4 extends slightly below seat H toprevent any liquid in cup 8 from reaching flue 55" in the event the pipeshould be moved around or turned over.

This invention operates on the principle of 45 the close association ofnicotine, tobacco tar, certain acids and carbon with moisture at hightemperatures, and by their partial elimination the smoker might enjoy adryer and milder smoke with many of the astringent elements which deadenthe senses of taste and smell removed, leaving a finer tobacco flavor tobe enjoyed. Experimentally many smokers who have been unable to smokeother pipes without distress of densing chamber 4 transversely. acrossthe path 16" metal sleeve between tobacco holder 2' and heart burn andstomach disorder can smoke pipes embodying my invention without sucheffects.

Varying constructions are shown in Figures 3, 4 and 5. They illustratecondenser chamber 4 with a metallic lining l2, with an annular flangeforming seat II. This lining is held in place by means of a metal tubeIS in flue section 5 passing through the wall of lining [2 at M. Fig. 4shows battle 3 to be solid instead of tubular as in Figures 2 and 3 butis not as eflicient in condensing moisture as the tubular construction.In Figure 5 the preferred bafile is omitted and depends for condensationon the agitation of the draft upon the gap between sections 5 and 5' ofthe flue but has in common with the other constructions the removablereservoir cup 8.

The assembly of the various elements of the pipe embodying my inventionnot only gives a unique appearance, but provides for a place in theplastic or rubber stem for the condenser, which admits of threading forthe engagement of baflle 3, though the condenser could be installed inshank I as shown in Figure 7. The installation of the condenser near theend of removable stem l makes it easy to clean, by disengaging it fromshank 'l and giving it several hard flicks, making it unnecessary tounscrew cup 8-except for thorough cleaning.

In Figure 8 the tubular condenser 3" is shown in a cigar or cigaretteholder being installed in a stem I.

In the operation of my invention it will be found that after smokingfrom one to three pipe fulls of tobacco that reservoir cup 8 will befull of brown liquid with some solids deposited on the side of bafile 3and in cup 8. A plurality of. bafiles 3 may be furnished with each pipe,each varying form the other in thermal conductivity, as Duralumin,aluminum and copper, so that the smoker can adapt the strength andflavor of the smoke to his taste, by the selection of the desiredbafile.

I do not claim that moisture does not condense in other pipes, whichsometimes wets the bowl and also be drawn into the mouth, but what I doclaim, and desire to secure by Letters Patent is:

1. A tobacco pipe comprising a tobacco bowl, a stem containing a fluethrough which the draft of the products of combustion is drawn, a metaltube extending transversely through said draft and communicating withthe outside atmosphere, and a removable reservoir cup surrounding oneend of said tube.

2. A tobacco pipe comprising a tobacco bowl, a stem containing a fluethrough which the draft of the products of combustion are drawn, a tubeextending transversely through said draft and communicating with theoutside atmosphere, and a removable reservoir cup surrounding one end ofsaid tube.

3. Atobacco pipe comprising a tobacco bowl, a stern containing a fluethrough which the draft of the products of combustion are drawn, a tubeextending transversely through said draft and communicating with theoutside atmosphere, said tube having an annular flange at one endforming the bottom of a condensation reservoir, and exposed to theoutside atmosphere.

4. A tobacco pipe comprising a tobacco bowl, a stem containing a fluethrough which the products of combustion are drawn, a bafile barextending transversely into said flue and a removable reservoir cupsurrounding one end of said baffle bar.
